Shure BLX2/SM58=-H9 Wireless SM58 Handheld Transmitter

The Shure BLX2/SM58=-H9 is a wireless handheld transmitter built around the iconic SM58 dynamic vocal microphone capsule — the same unidirectional cardioid capsule that has been a live sound staple for decades. Designed to work within Shure's BLX wireless system, this transmitter provides clean, professional-grade audio with an operating range of up to 300 feet, giving performers and presenters the freedom to move naturally across a stage, through a venue, or into an audience without worrying about signal dropouts. The transmitter's user-friendly interface keeps operation straightforward, with accessible controls for quick adjustments during soundcheck or mid-show.

Practicality is central to the BLX2's design. A pair of standard AA batteries delivers up to 14 hours of continuous use, easily covering back-to-back sets, full-day conferences, or house-of-worship services. The metal construction provides the rugged durability expected in professional and semi-professional environments, and the included mic clip and batteries mean you can be up and running immediately. With support for up to 12 channels per frequency band, the BLX system scales for multi-mic setups. The key consideration is that this is a transmitter-only component operating on the H9 frequency band — a matching Shure BLX receiver in the H9 band is required and sold separately, so confirming frequency compatibility with your region and your existing gear is essential before purchase.
